These compounds of Formula II and their preparation are disclosed in my aforesaid applications Serial Nos. 533,510 and 533,511, the disclosure of which is hereby incorporated by reference. a I a To illustrate more particularly the preparation of the new quaternary compounds, a compound of Formula may be obtained in either of two ways. The first method involves the exhaustive methylation of N (B-aminoethyl)-N,N'.-ethyleneurea. This may be accompanied by means ofa methyl halide, Bromide or iodide or by other methylatingagents, such as dimethyl sulfate, the methyl ester of p-toluenesulfonic acid a'ndthe 'r'r'iethyl ester of benzenesulfonicya'cid. Illustratively,;'one mole of the aminoethylethyleneurea may be reactedwiththree moles of themethylating agent, suchas methyl chloride, in'the presence of an alkaline material, such as sodium carbonate in an'alcoholic solution such as in ethanol, isopro panol, amyl alcohol, n-butanol and tert-butanol. "The quaternary ammonium compound is soluble in ethanol even in thecolid and consequently, to facilitate separation of the product, it is preferable to use a higher alcohol such as butan'ol in which the product is soluble at elevated temperatures-but insoluble in the cold so that, on cooling, theprodu'ct may be readily precipitated and removed by filtration. The N (,8+aminoethyl)-N,N- ethyleneurea and the alkylating agent are reacted by heating to a temperature between 60 C. and '200" C. for a time which is generally longer at the lower temperature and shorterat the higher temperature. For example, reaction is"preferaibly "carried out at reflux, and when butanolis used a period of about eight to ten hours at the reflux. temperature of about 120 C. is generally adequate. At 200 C., a period of three hours may be ade- (mate, and a period of 24 hours is generally satisfactory at abqmsm 'C. The preferred range of temperature is from 90jto 130 C. for a period of time from seven to twelve hours. If desired, reaction may be carried out in the alcoholic solvents under superatrnospheric pres sure tofa cilitate the attainment of higher temperatures with anypa'rticular alcohol and thereby reduce the time needed. 1

Generally the methyl chloride or other alkylating agent may be added continuously throughout the reaction period'mFor example, in a batch containing about one grarn'f mole weight of the N-(B-aminoethyl-N,N-ethyleneurea, theimethyl chloride may be added at a rate of about 250cc. per minute throughout a ten-hour period. Completion of the reaction is readily detected by determiningwh'en'carbon dioxidc is no longer evolved. On completion of the reaction the .sodium chloride which is undi ssolved is Tfiltered off,and the filtrate is chilled to precipitatethe,productwhensuch an alcohol as butanol The N-(fi-chloroethyl)-N,N'-ethyleneurea may be prepared by reacting thionyl chloride (S001 with N-(phydroxyethyl) N,N-ethyleneurea. The two reactants may be used in approximately equimolar amounts and reaction is preferably effected with the urea dissolved in chloroform. Preferably the thionyl chloride is added gradually. For example, when the reaction involves a batch containing about two moles of the urea, the thionyl chloride may be added over a period of two hours. The reaction is preferably effected at a temperature of C. to 100 C. Advantageously, it may be carried out with the chloroform at reflux at a temperature of about 58 to 66 C. After completion of the addition of the thionyl chloride, the chloroform may be gradually distilled while introducing toluene until the temperature in the vessel reaches about 105 to 109 C. It is then refluxed for about 20 hours in the toluene. The product is soluble in the hot toluene which is cooled to about 5 to 10 C. or lower to precipitate the N-(fl-chloroethyl)-N,N'-ethyleneurea. The precipitated product may then be filtered and, if desired, washed with cold toluene. It is then air-dried or dried under a vacuum at room temperature. It has a melting point of 82 to 83 C.

, cellulose; antistatic agents for application to articles made is used. Filtration is repeated and after an optional washing with 'butanol, thelproductmay be dried either at normaltroom temperatures or at elevated temperatures up tol2$ C.

An alternative method to produce a compound of FormulaIII is to reacttrimethylamine with N gs-chloroethyl)-N,N ethyleneurea. The reactionof this urea clerivative with the trimethylamine may be effected in a solvent for the urea, such as benzene, toluene, xylene, or even in water or alcohols such as the :alc'ohols mentioned above. The temperature of reaction may be from room temperature for a period of 24 hours ormore up to 200 C. for a period of 15 minutes or so. Preferably. the reaction is effected at a'temperature'of 80 C.'to 120 C. for one 'to eight hours or more, particularly at 100 'C. for three to sixhour s. The quaternary product is insolublein the hydrocarbon solventsmentioned so that it maybe removed merelyby filtration. The filtered product may optionally bewashed with benzeneor other hydrocarbon solventand ma then be dried 'at room temperature or at somewhat elevated temperature up to 120. (3. a

e If desired, reaction may be" effected under'pressure such as at about 25 poundsper'square inclrgaugeto obtain highertemperatures fora give'nsolvent. The pres sure mentioned forexample is adequate to raise the temperature to about 100 C. when the reaction is effected in benzene, or in the alcohols.

of hydrophobic materials, such as fibers, films, yarns, textile fabrics, and other shaped articles formed of vinyl resins, such as polyvinyl chloride, polyvinylidene chloride, polyacrylonitrile, copolymers of vinyl chloride, vinylidene chloride, and acrylonitrile with each other or with other comonomers including vinyl pyridines, vinyl acetate, methyl acrylate, other acrylates or methacrylates, also nylon and polyesters, such as polyethylene terephthalate.

Besides being useful as chemical intermediates in the preparation of other compounds, the quaternary ammonium compounds of Formula I are useful as fungicides, bactericides and insecticides. They also serve as softeners for cellulosic materials such as regenerated cel- 'lulosctcellbphane), rayon, cellulose acetate, and also as antistaticagents for cellulose esters such as cellulose acetate, cellulose acetobutyrate; also for nylon, Dacron (polyethylene terephthalate); for polymers of acrylonitrile containing to of acrylonitrile with other comonomers such as vinyl chloride, vinyl pyridine, or mixtures thereof, such as Orlon and Acrilan; for polyvinyl chloride, and copolymers of 75% to vinyl chloride'with vinyl acetate or vinylidene chloride with acrylonitrile.

Those. compounds of Formula I in which.'R is the vinyl group may be polymerized or copolymerized, or polymers and copolymers of a compoundof Formula II in which R is the vinyl group maybe quaternized by means of an alkylating agent R Y under essentially the same conditions as those described above in regard to the quaternization of the monomeric compounds of Formula II.

The polymerization of the compounds of Formula I or II in which R is a vinyl group may be effected by an addition mechanism in bulk, solution, emulsion, or suspension technique using any'suitable free radical catalyst, but preferably in azo type. In the solutionprocedure, such solvents as water, dioxane, 01' a lower alcohol, including ethanol and isopropanol, may be used. A water-insoluble vinyl compound of Formula I or II is readily adaptedto the emulsion technique of polymerization. Even the water-soluble monomers are useful in a suspension technique if brine is used.

The polymerization is effected with the aid of a free radical initiator or catalyst, such as an organic or inorganic peroxide catalyst, peroxy catalysts, such as persulfates, and the azo catalysts. From 0.1% to 3% or more of the initiator or catalyst may be used, based on the total weight of the monomers. To provide a high molecular weight, it is preferred to use from 0.5% to 1% of the initiator. Examples of organic peroxide catalysts that may be used include benzoyl peroxide, acetyl peroxide, caproyl peroxide, butyl perbenzoate, butyl hydroperoxide. Examples of azo catalysts include azo'diisobutyronitrile, azodiisobutyramide, dimethyl or diethyl or dibutyl azodiisobutyrate, azobis(a,' -dimethylvaleronitrile), azobis(a-methylbutyronitrile), azobis(umethylvaleronitrile), dimethyl or diethyl azobismethylvalerate, and the like.

In the case of emulsion polymerization particularly, a redox system is extremely eifective. Here an organic peroxide may be used or an inorganic peroxide such as hydrogen peroxide, ammonium persulfate, sodium persulfate, or potassium persulfate,in amounts similar to those stated above. The peroxidic catalyst is effectively coupled with a reducing agent such as an alkali metal sulfite, bisulfite, or metabisulfite, or hydrosulfite, or hydrazine. The action of the redox system may be controlled through use of a chain transfer agent or regulator, such as mercaptoethanol or other mercaptan. Such regulator also finds use outside of redox systems with organic or inorganic peroxides and with azo catalysts, such as azodiisobutyronitrile, azodiisobutyramide, or diethyl azodiisobutyrate.

When a solution technique is used, the direct product of the polymerization is a viscous solution of the polymer, or it may be that the polymer is precipitated from the solution depending upon the particular solvent, the particular monomers and their properties. When the polymers automatically precipitate because of their insolubility in the solution, it is merely necessary to filter the product and wash the polymer in order to isolate it. When the product is a viscous solution of the polymer, it may be precipitated by adding a solvent for the polymerization solvent in which the polymer is insoluble after which the suspension or slurry may be filtered or decanted and the polymer washed; Alternatively, the solvent may be distilled to leave the polymer.

In the case of emulsion polymerization, examples of suitable non-ionic emulsifiers include the higher alkyl phenoxypolyethoxyethanols in which the alkyl has from 6 to 18 carbon atoms, such as octyl, dodecyl or octadecyl, and there may be from 8 to 50 or more oxy ethylene units. Examples of anionic emulsifiers include the higher fatty alcohol sulfates, such as sodium lauryl sulfate; examples of cationic emulsifiers include higher alkyl pyridinium salts such as lauryl pyridinium chloride, (octylbenzyl)trimethylammonium chloride, and so on. Examples of vinylidene or monoethylenically unsaturated compounds that may be copolymerized with a compound of Formula I or II include vinylpyridines, such as 2-vinylpyridines and 4-vinylpyridines, acrylonitrile, methacrylonitrile, acrylic and methacrylic acids, their esters, amides and salts, itaconic acid and its functional derivatives, particularly its esters, maleic anhydride or maleic and fumaric acids and their esters, vinyl ethers and esters, vinyl sulfides, styrene and its homologues and analogues, vinylpyridine, vinylcarbazol, and allyl esters of monocarboxylic acids. Specific ethylenically unsaturated compounds are methyl, ethyl, isopropyl, butyl, tert-butyl, octyl, dodecyl, octadecyl, octenyl, or oleyl acrylates or methacrylates or itaconates, dimethyl maleate or fumarate, diethyl maleate, diethyl fumarate, diethyl citraconate, diethyl. chloromaleate, dimethylaminoethyl acrylate or methacrylate, tert-butylaminoethyl.acrylate.or

methacrylate, dimethylaminopropyl acrylate or methacrylate, acrylamide, methacrylamide, N-methylacrylamide,

N-butylmethacrylamide, 'dimethylaminoethylacrylamide,

dimethylaminopropylacrylamide, or the comparable methacrylamides, hydroxyethyl vinyl ether, octyl vinyl ether, dodecyl vinyl ether, ureidoethyl vinyl ether, ureidoisobutyl vinyl ether, ethyl vinyl ether, butyl vinyl ether, butyl vinyl sulfide, methyl vinyl sulfide, dodecyl vinyl sulfide, vinyl acetate, vinyl propionate, vinyl laurate, amethylstyrene, p-methylstyrene, p-chlorostyrene, vinylnaphthalene, etc. When two or morefree radical-polymerizable vinylidene groups occur, as in divinylbenzene, trivinylbenzene, ethylene diacrylate or methacrylate, bis- (vinyloxyethyl)urea, or vinyloxyethyl acrylate or methacrylate, insoluble interpolyrners result.

The polymers and copolymers are useful as fungicides, bactericides, and insecticides. They also serve as softeners for cellulosic materials such as regenerated cellulose (cellophane), rayon, cellulose acetate, and also as antistatic agents for cellulose esters such as cellulose acetate, cellulose acetobutyrate; also for nylon, Dacron (polyethylene terephthalate); for polymers of acrylonitrile containing to of acrylonitrile with other comonomers such asvinyl chloride, vinyl pyridine, or mixtures. thereof, such as 'Orlon and Acrilan; for polyvinyl chloride, and copolymers of 75% to vinyl chloride with vinyl acetate or vinylidene chloride with acrylonitrile.
